2018-01-24brcmfmac: separate firmware errors from i/o errorsArend Van Spriel
When using the firmware api it can fail simply because firmware does not like the request or it fails due to issues in the host interface. Currently, there is only a single error code which is confusing. So adding a parameter to pass the firmware error separately and in case of a firmware error always return -EBADE to user-space.

In the bcdc protocol it can return value above 0 and we carry a fix in the caller of the protocol layer api. This patch makes it adhere to the intent of the api as described above.

2018-01-16brcmfmac: fix CLM load error for legacy chips when user helper is enabledWright Feng
For legacy chips without CLM blob files, kernel with user helper function returns -EAGAIN when we request_firmware(), and then driver got failed when bringing up legacy chips. We expect the CLM blob file for legacy chip is not existence in firmware path, but the -ENOENT error is transferred to -EAGAIN in firmware_class.c with user helper. Because of that, we continue with CLM data currently present in firmware if getting error from doing request_firmware().
